Shelters and safe rooms routinely are tested to withstand storms of various intensities. The force of a storm usually is measured on the "F scale."
Fujita-scale forum: In 1999, Texas Tech University's Wind Science and Engineering Research Center proposed an official examination of the problem that could be used to create an enhanced F-scale meeting the needs of the "meteorological and engineering communities."
